The latest in a wave of bomb threat hoaxes called into more than 20 Jewish community centers and schools across the country has again put administrators in the position of having to decide whether a threatening message on the other end of a phone line was enough to evacuate.

The suspect, who was not named by police, is 19 years old, the Associated Press reports.

Police spokesman Mickey Rosenfeld said the suspect's motives were unclear. Since dozens of Jewish centers have received bomb threats in recent weeks, it is not clear which calls were made by the suspect.

Rosenfeld said the suspect used advanced technology to mask the origin of his calls. He also made threats in New Zealand and Australia.

The FBI and other nations' police assisted in the investigation, Rosenfeld said.
